Subject: [PATCH v6 2/2] arm64: dts: cix: add sky1 DMA-350 node with channel IRQ entries
Date: Wed, 25 Mar 2026 19:21:59 +0800 [thread overview]
Message-ID: <20260325112159.663881-3-jun.guo@cixtech.com> (raw)
In-Reply-To: <20260325112159.663881-1-jun.guo@cixtech.com>
Describe the DMA-350 channel interrupt sources in DT using 8
interrupt entries, while all entries map to the same GIC SPI
as wired on this platform.
